Vishay Draloric
Axial Vitreous Leaded Wirewound Resistors with CECC Approval,
Available with Established Reliability
FEATURES
• CECC 40201-801 approval options:
- Version A, failure rate level E0
- Version E, with established reliability, failure
rate level E7
• High power dissipation in a small design
• Excellent pulse load capability
• Vitreous coating
• Non-flammable and enhanced humidity protection
The FDG, FDK and FDP resistors, with completely welded
construction, are the perfect choice for high continuous
power dissipation up to 11.5 W. The established reliability
and failure rate level E0 and E7 is demonstrated within
CECC qualification. The components of this series are well
suited for harsh environments and exhibit a long lifetime.
With their high pulse power capability, they are the ideal
choice for inrush limiters. Typical applications include but
are not limited to power supplies, voltage dividers, AC filters,
and snubber resistors. Particular requirements can be

Notes
•
•
The operating temperature range for these resistors is from -55 °C up to 350 °C
The failure rate level E7 (10-7/h, Q = 0.1) corresponds to MIL Level R, is superior to level E6 (10-6/h, Q = 0.3) or level E5 (10-5/h, Q = 1)
and thus may be used as a replacement

Resistance values are to be selected for 5 ꢀ from the E12 series, and for 2 ꢀ from the E24 series
